There is a special form of a quadratic that is best for graphing the equation. We'll analyze it thoroughly here. Here y0 is the y coordinate of the vertex, x0 is the x coordinate of the vertex, and a is the amplitude, a measure of the thickness of the parabola.
Comments: Comments Off. According to the U.S. Geological Survey the average person uses between 80-100 gallons of water per day and estimates that 95% of the water we use, goes down the drain (1). So we waste 76-95 gallons per day. A shower, for example, uses between 2-5 gallons per minute.A dishwasher uses between 4-10 gallons of water for each load.

Since 1950 the United States Geological Survey (USGS) has produced water use reports every five years to give a detailed look at how the United States uses water. The most recent USGS estimates show that in 2005 average water withdrawals was about 410 billion gallons per day (BGD) from fresh and salt water sources.
